Taylor Swift performs during The 1989 World Tour at Tokyo Dome at Tokyo Dome on May 6, 2015 in Tokyo, Japan.

Following up announcements that Lena Dunham, Zendaya, Kendrick Lamar and more would be appearing (via alter egos) in Swift's buzzy latest music video, today the singer announced that singer-actress-model Serayah, a.k.a Dilemma, would also show up.
